< cpp‎ | atomic‎ | atomic

T load( std::memory_order order = std::memory_order_seq_cst ) const noexcept; | (1) | (since C++11)
T load( std::memory_order order = std::memory_order_seq_cst ) const volatile noexcept; | (2) | (since C++11)

Atomically loads and returns the current value of the atomic variable. Memory is affected according to the value of order.

If order is one of std::memory_order_release and std::memory_order_acq_rel, the behavior is undefined.

It is deprecated if std::atomic<T>::is_always_lock_free is false and overload (2) participates in overload resolution. | (since C++20)

### Parameters

order | - | memory order constraints to enforce

### Return value

The current value of the atomic variable.
